ALBERT J'. MQCAULEY, OF ST. LOUIS, MISSOURI.

CAR-TRUCK.

To all whom it may concern:

Be it known that I, ALBERT J. MOCAULEY, a citizen of the United States,residing at St. Louis, Missouri, have invented a certain new and usefulImprovement in Car-Trucks, of which. the following is a full, clear, andexact description, such as will enable others skilled in the art towhich it appertains to make and use the same, reference being had to theaccompanying drawings, in which Figure 1 is a side elevation, partly insection, of a car truck embodying the features of this invention; Fig. 2is a top or plan view of the truck shown in Fig. 1; Fig. 8 is aperspective view showing the end portion of a side frame; Fig. 4 is aperspective view of one of the removable sections which are applied tothe side frames to close the journal receiving openings; Fig. is a planview, partly in section, of the parts shown in Fig. 3; Fig. 6 is alongitudinal sectional view taken approximately on the line 6 6 of Fig.5; Fig. 7 is a sectional view taken approximately on the line 77, Fig.6; and Fig. 8 to Fig. 12 inclusive are sectional views, illustratingmodifications.

This invention relates to improvements in car trucks; the main objectbeing to produce a car truck in which the wheels and axles can be easilyremoved from connected side frames.

To remove the wheels and axles from j ournal boxes formed integral withside frames, it is necessary to dismantle the truck by disconnecting thetwo side frames and then moving the side frames away from each other toseparate the journals from the journal boxes. To avoid this laborvarious divided or separable journal boxes have been devised, suchstructure including journal box sections cast integral with the frameand removable journal box sections fastened onto the frame by means ofbolts or similar fastening devices. It is quite ditlicult to produce andmaintain a tight, dust proof joint between the separable edges ofjournal box sections that are merely connected by bolts or other similarfastening devices, because such fastening devices are liable to workloose when the truck is in service.

Therefore, one of the objects of this invention is to provide a journalbox structure comprising separable sections which are forced intoengagement with each other by the weight of the car body and truckframe, thereby producing and maintaining an abso- Specification ofLetters Patent.

lutely tight joint at the separable edges of the sections.

Other objects and advantages as well as the novel details ofconstruction will be hereinafter pointed out.

In the preferred form of my invention each side frame is a casting, openat the top to receive the journals, and removable sections which supportthe frame constitute the top walls of these openings. The side framesmay be permanently connected together. To remove the wheels and axles,the side frames are raised to disengage the removable sectionstherefrom, and thereafter said sections are removed to allow thejournals to pass out through the journal receivmg openings.

In the accompanying drawings :-F designates side frames, preferably, butnot essentially, of the diamond type. The side frames may be connectedby a spring plank S and a bolster B or any other suitable connectingdevices. Each side frame F is preferably a casting having lubricantreceptacles L integrally connected to its ends, said lubricantreceptacles being open at the top to receive journals J which extendfrom the wheels W.

Referring more particularly to Figs. 3 to? inclusive, it will be notedthat each lubricant receptacle comprises side walls 1 and 2 integrallyconnected by a curved bottom wall and also integrally conected at thetop by a bridge 3. The side walls have inturned top flanges at. Acomplete door frame 5 is formed integral with the lubricant receptacle,and the usual door or lid 6 may be used with this door frame. Ribs 7 and8 extending around the side and bottom walls of the lubricant receptacleprovide grooves for the reception of a dust guard 9. As the side frameis open at the top it is preferably reinforced by one or more ribs 10extending around the bot tom and outer walls of the lubricant receptacleand it may also be strengthened by ribs 11 at the side edges of theopening. Each journal receiving opening extends from the inner face .ofthe frame to a point near the outer edge thereof and said opening isnormally closed by a removable section B. The bridge 3 and flanges 4forming the side and front walls of the journal receiving opening areprovided with closure seats which lie above and rest on the side andfront margins of the removable section B. The usual brass or bearing 12is seated on the journal J and the usual wedge 13 is interposed betweensaid bearing and the removable section B. The removable section Rconstitutes a wedge seat and it is preferably provided with one or morewedge stops 14: (Fig. 6). The bearing stops 15 are integral with theside frame.

Fig. 1 and Fig. 7, show that the side frames are supported by thejournals, the load being transmitted through the sections 11, bearings12 and wedges 13. As the weight of the side frames is transmitted to thejournals through the removable sections R which span the journalreceiving openings it will be understood that said frames are alwaysfirmly forced onto the members It so as to produce an absolutely tightjoint around each journal receiving opening.

Each removable section R is interlocked with the bridge 3 as shown inFig. 6, and also interlocked with the under side of the flanges 4 asseen in Fig. 7. It should be noted that the truck frame is heldinterlocked with the removable sections by the pressure of its ownweight. As the removable sections are interlocked with the flanges 4 atthe upper edges of the opposite side. walls 1 and 2, said side walls arepositively connected to each other by the removable sections.

If desired, the removable sections may be connected to the side framesby means of fastening devices, each of the sections I have shown beingprovided with an car 17 having an opening 18 for the reception of asplit key 19, one end of which is seated on a flange at, see Figs. 3 toThe removable sections R preferably overlap the dust guards 9 and may beprovided with grooves to receive the upper ends of the dust guards (Fig.6).

In removing the wheels and axles, the connected side frames are raisedto allow the removable sections to be disengaged from the lubricantreceptacles, and the bearings 12, Wedges 13, and remoable sections B maythen be removed through the door frames 5. Thereafter, the side framesmay be dropped to allow the journals to pass over the top faces of thelubricant receptacles.

As a high degree of accuracy can not be obtained in making the largeside frame castings, packing P is preferably interposed between theremovable sections R and the side frames (Figs. 4, 6 and 7). Thispacking is compressed around the journal receiving openings by thecombined weight of the truck frame and car body. The packing P may beformed by strips of fiber, leather, waste, or any other suitablematerial, but it is preferably lead or some other soft metal which willyield in response to pressure and thereby form a seal between theremovable sections and the side frames.

Fig. 8 illustrates a modification in which a metal dust guard 20,interlocked with the lubricant receptacle L has a flange 21 whichsurrounds the journal and extends beyond the inner face of the lubricantreceptacle.

Fig. 9 shows a lubricant receptacle having its opposite side wallsconnected by a removable section R, said walls having down turnedflanges which engage the packing P.

Fig. 10 illustrates a removable section B which forms the top wall and aportion of a side wall of the lubricant receptacle L.

Fig. 11 and Fig. 12 illustrate a structure in which the removablesection R has a pair of depending flanges 22 which are interlocked withthe lubricant receptacle L so as to constitute hangers for the sideframe F.
